Monty Hall Problem’s Simulation Using Pygame

In this article, we are going to see how to create Monty Hall games using Pygame in Python. Monty Hall was a game show of the American television game show Let’s Make a Deal.

Suppose you’re on a game show, and you’re given the choice of three doors, Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice?

Demo of what the end product would look like:

The goat is revealed to behind door 1. Original selection was door 2.

As the decision was made to stay, the game is won.
